When: Day 1 : Sunday May 21st

Today's architecture modelling environment suffers from being an effort to satisfy milestone decisions. Typically, the architecture effort is separated from the Systems Engineering (SE) leading to a lack of traceability from the systems requirements to the architecture resulting in interoperable systems. Due to the way that the Architecture models are created they generally consist of static diagrams and provide limited analytical support to the decision maker.

Undergoing paradigm shift from document-centric systems engineering approach to Model-Based Systems Engineering (MBSE) revealed gaps of the MBSE approach. In example, to successfully apply language like SysML, questions like how to structure the model, what views to build, which artefacts to deliver and in what sequence need to be answered.

Applying the Unified Architecture Framework (UAF), previously known as Unified profile for MODAF and DoDAF (UPDM), using an MBSE approach moves the architecture modelling effort to one that is an integral part of SE, helping the systems integrator to develop interoperable systems, with traceability to requirements and across views, using one integrated architecture model that enables impact analysis, gap analysis, trade studies, simulations, and engineering analysis. Moreover, the scope of UAF is expanded beyond defence architectures. It is genericized to be applicable to architecting systems of systems of any domain.

This tutorial explores how to leverage MBSE with architecture modeling in an integrated and disciplined approach, enabling the modernization of complex systems. Tutorial is based on an industry case-study and features the creation of architecture from A to Z, combining both theory and practice.
